9 9. Reduce on-site emissions by using equipment that burns propane/natural gas instead of gasoline. Electric equipment eliminates combustion emissions. 10. Exhaust pollution sources directly to the outside using temporary or permanent ventilation equipment (refer to HVAC Protection Measures). 11. Where exhaust is not feasible and ventilation is required, locally re-circulate air through a portable air cleaner. 12. Collect and bag sawdust from woodworking tools. 13. Cover and/or seal all indoor sources of odor and dust. 14. Use painting techniques that minimize odor (roller instead of spraying) 15. Use cleaning practices that minimize dust (vacuum instead of sweeping). 16. Use cleaning products that minimize pollution, fumes, VOC s, chemicals. 3.4 CONTAINMENT IAQ POLLUTANT MEASURES A. Prevent the movement of pollutants from the source to other areas in the building as follows: B. Erect dust curtains/doors/barriers C. Use portable fans to exhaust pollutants (e.g. gas engine exhaust) to the exterior through windows, doors, etc. Ensure that other windows or doors will not let pollutants back into building. D. Close windows and doors close to exterior work do not allow exterior pollutants to enter the building (dust, vehicle emissions, etc.). If windows and doors are not yet installed, temporarily seal openings with plastic, wood, etc. E. Move equipment or pollutant-causing work to locations where IAQ impact is minimized: 1. Avoid high draft or large open areas 2. Use shields and curtains to contain work 3. Locate in small, contained areas 4. Locate outside the building 5. Depressurize the work area using temporary or permanent ventilation equipment (refer to HVAC Protection Measures). 6. Pressurize occupied or completed areas using temporary or permanent ventilation equipment (refer to HVAC Protection Measures). 3.5 HOUSEKEEPING MEASURES A. Clean frequently to collect dust. B. Minimize creation of dust during cleaning by using wetting agents, sweeping compounds, damp rags, wet mop. C. Use vacuum equipment with HEPA filtration and/or a wet scrubber. D. Clean spills promptly. E. Clean or remove excess application of solvent-containing products. F. Remove accumulated water and keep the building interior as dry as possible. INDOOR AIR QUALITY
